Stanislav said...Hi all,
I have to add following information.
Before you start removing Oracle software on Windows OS, you ought to stop all oracle services.
ravi krish said...app\oracle\product\10.2.0\server\BIN\oci.dll & msvcr71.dll are not getting deleted
Mehul said...Very usefull !!
It would be better to delete also all the classpath variables related to oracle and oracle_home if it is set.
arona said...What about the oraInventory directory under UNIX.
You did not mention it

Khalid Beg (mkb47) said...Thanks Tim. The steps are very useful and easy to catch for any TECH guys. The most important thing is that IT WORKED SMOOTHLY on windows7
Andrew said...As stated several times above. OracleHome\Product...\oci.dll is being used by what looks like the following 2 services:
All reference to Oracle has been removed from registry and reboot do not clear these services from task manager. This is Windows 7
The process works for me. I suggest you check the services have been deleted from the registry.
Also, try renameing the dll, then reboot. Often, if the delete won't work, the rename will. This will prevent anything from trying to use it after reboot.
I have sucessfully unintalled Oracle 10g.Thank you so much for your help.
Stuart said...You can also detach an Oracle home from the inventory. I've had to do this on my EM agent11g home after it wouldn't deinstall via normal methods. Also applies to db homes.
./runInstaller -silent -detachHome ORACLE_HOME="/u04/app/oracle/product/11.2.0/agent11g" ORACLE_HOME_NAME="agent11g1"
Rodger said...Don't forget to remove any environment variable references, otherwise any subsequent re-install may fail (because they still refer to folder paths that don't exist).
Richard said...On Windows also remove C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Oracle*
Awesome. I've added that in. Thanks for pointing it out. :)

kyte said...i followed your steps and successfully deleted my oracle.. but what happened is that i haven't regained any disk space at all.. as if it was just hidden but still using my disk space.. prior to deleting the oracle folder, i had 207Gb free space.. but after deleting it, it is still 207Gb.. how can i recover my disk space? i really need help here..
If you deleted the items using Windows Explorer or a GUI on UNIX/Linux, the deleted items may be in the recycle bin. Empty it.
If that doesn't help, reboot.
DO NOT ask technical questions here! They will be deleted!
